Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F57266ADFP#30 | Same SH-2A core but with 2 MB Flash, no USB, added Ethernet MAC; uses 176-pin LQFP. | Better suited for gateway ECUs requiring TCP/IP stack and larger firmware image storage. | Select when Ethernet connectivity and >1.5 MB code space are mandatory; requires PCB redesign due to pin count and layout. |
| RA6M5GFP128A | Arm Cortex-M33 core, TrustZone, 1 MB Flash, same 144-pin LQFP; lacks native CAN FD but adds Octa-SPI. | Targets secure IoT edge nodes needing PSA Certified Level 2, not automotive ASIL-B. | Choose for new designs prioritizing long-term Arm ecosystem support and security certification over legacy SH toolchain continuity. |
Compared with R5S72640P144FP#UZ, R5F57266ADFP#30 offers higher memory density and networking capability at the cost of USB omission and larger footprint, while RA6M5GFP128A provides modern security features and Arm toolchain alignment but requires functional re-architecture to replace SH-2A-specific FPU and CAN timing behavior.

FAQ
What is the maximum operating temperature range for the R5S72640P144FP#UZ?
The R5S72640P144FP#UZ is rated for operation from −40 °C to +125 °C ambient temperature, qualified per AEC-Q100 Grade 2 standards. This extended range supports under-hood automotive deployment and industrial environments with high thermal stress. The device includes on-chip temperature sensor and thermal shutdown logic that triggers at 150 °C junction temperature to protect R5S72640P144FP#UZ functionality.
Does the R5S72640P144FP#UZ support CAN FD or only classical CAN 2.0B?
The R5S72640P144FP#UZ supports CAN 2.0B only - it does not implement CAN FD protocol features such as variable bit rates or extended data length. Its two CAN modules comply fully with ISO 11898-1:2015 for classical CAN at up to 1 Mbps. For CAN FD requirements, Renesas recommends migrating to the RH850/F1K series or RA6T2, not R5S72640P144FP#UZ.
Is the R5S72640P144FP#UZ pin-compatible with other SH7264 family members like R5S72641 or R5S72642?
No, the R5S72640P144FP#UZ is not pin-compatible with R5S72641 or R5S72642. While all share the 144-pin LQFP package, pin functions differ significantly across variants - for example, R5S72641 relocates USB D+/D− signals and disables one CAN channel. Migration requires schematic and layout revision; R5S72640P144FP#UZ pinout is unique to its Flash/RAM configuration and peripheral enablement.
What development tools are officially supported for firmware development on the R5S72640P144FP#UZ?
Renesas provides official support for the R5S72640P144FP#UZ via CS+ (formerly High-performance Embedded Workshop), e2 studio with GCC-based toolchain, and the Renesas Flash Programmer. Debugging requires E2 emulator Lite or E2 emulator Pro. The R5S72640P144FP#UZ is also supported in the Renesas Motor Workbench for FOC implementation, and its FPU is validated against SH-2A FPU compliance test suite v3.2.
How is functional safety certification handled for the R5S72640P144FP#UZ in ASIL-B systems?
The R5S72640P144FP#UZ is certified to ISO 26262 ASIL-B at the component level, with FMEDA reports, safety manuals, and diagnostic software libraries provided by Renesas. Key safety mechanisms - dual-lockstep CPU monitor, ECC on memories, and windowed WDT - are documented in the R5S72640P144FP#UZ Functional Safety Manual (R01US0134EJ0400). System-level ASIL decomposition must be performed separately per OEM requirements.
